The typical closed ball mill circuit to which CSE analysis can be applied is shown in Fig. 1. The extreme importance of the circulating load ratio (solids tonnage through the mill vs. the circuit) in determining circuit productivity was demonstrated by Davis (1925) and published by Gaudin. (1939), as shown in Fig. 2. The circuit
Shortly after the first applications of closed circuit ball mill grinding it was realised that classification increases mill capacity. Therefore, over the years closed ball mill cyclone circuits have become an industry standard. Although mill capacity increases with circulating load, an optimum circulating load of 250% was
